The term of “tsunami” comes from the Japanese which means harbour ("tsu") and wave ("nami"). A tsunamigk is a series of waves generated when water in a lake or the sea is rapidly displaced on a massive scale.
A tsunami can be generated when the sea floor abruptly deforms and
vertically displaces the overlying water. Such large vertical movements
of the earth's crust can occur at plate boundaries. Subduction of
earthquakes are particularly effective in generating tsunamis, and occur
where denser oceanic plates slip under continental plates.
As the displaced water mass moves under the influence of gravity to
regain its equilibrium, it radiates across the ocean like ripples on a
pond.
Tsunami always bring great damage. Most of the damage is caused by the
huge mass of water behind the initial wave front, as the height of the
sea keeps rising fast and floods powerfully into the coastal area.
